To all whom it may concern:

Be it known that LALBERT J. THOMAS, a

citizen of the UnitedStates, residingat the,

My invention relates to placing'advertisthe object thereofis to lock such advertising matter in the arms of chairs or seats in an attractive manner so that the occupant of the chair or seat will read the same.

Other objects will be hereafter explained.

I accomplish this object by the mechanism described herein and illustrated in the accompanying drawings in which; f

Figure 1 is a perspective View of a fragment of a rocklng chair, in one arm of which is placed advertising matter. Fig. 2 is a section on the line 2-2 of Fig. 3. Fig. 3 is a longitudinal central vertical section of ,a part of the arm. Fig. 4 is a detail of a part of the locking mechanism.

In the drawings 5 is a fragment oi an old mission style of rocking chair, and 6 is one of the arms thereof. This arm is longitudinally and horizontally divided, preferably in the center thereof. The lower half 6a is rigidly secured in the chair structure in the usual manner and in the upper surface thereof are recesses 7v which are covered by escutcheon shaped securing plates 8 which are counter sunk so as to be fiush, or a little below the surface, and are secured thereto by screws 9. These plates are provided with keyhole shaped apertures 10. Through the larger ends of these holes pass the heads of screws l1 which screws are' secured in the upper half 6" of the arm. There are preferably 4 of-these plates and 4 screws in each arm and they are so placed that after the heads of the screws have been passed through the holes in the securing plates the upper halfot the arml is moved rearwardly thereby causing the shank of the screw to enter the narrow portion of the hole in plate 9 thereby preventing the upper part of the arm from separating from the lower part. At aniv one of the recesses in the lower half of the arm a locking bolt 12 may be passed into the arm with the inner end thereof lying in the path of movement oi' theV head of the screw so as to prevent the longitudinal m0vement ofthe upper half of the arm upon the lower half thereby locking the' upper to the lower half. The head of this locking bolt is disk shapedand is provided with holes 13 in which are receivedxthe prongs ot' a wrench for turning the same. The shank adjacent to the headis screw threaded and is screwed vinto a thimble 14.- whichv is recessed in the 'lower surface ofi the arm. The inner end of the locking bolt may be smooth and reduced vin size. Any other means may used to lock the upper half to the lower half of the arm.

In the upper half of the arm is 'an aperture 15 which extends therethrouglntlie outer portion of which is contracted, preferably on a bevel as shown in Figs. 2 and 3. In the contracted portion is received a transparent plate, preferably a glass plate 15, Onthe back of this plate are placed 'advertising cards 16. These cards are held in contact with the glass plate by a back plate 17 preferably of thin metal suchas galvanized sheet iron. yThese plates and advertising cards are held with the outer surface of the glass plate flush with the top surface of the arm of the chair by securing blocks 18 to the backs of which are secured springs 19 the ends of which are received in recesses 2 0 in the side walls of the aperture.

' When it is desired to change the advertising matter the lookin bolt would be removed. The upper ha] of the arm would be moved longitudlnally'until the heads of the screws registered with the enlarged portion of the key hole-in the escutcheon plate when it could be lifted oli. The securing bars would then be removed. The back and advertising matter would be taken out. New advertising matter 4would be inserted and the parts replaced and secured in position.

Bythis construction a neat and attractive advertising chair or seat is provided in be i which advertising matter is held and locked panel; screws Secured in the upper portion of said arm and projecting from the under side thereof; plates secured to the lower half, having keyho1e shaped apertures through said plates, the larger portion of said apertures permitting the passage therethrough of the heads of the screws and the narrower portions retaining the heads of the screws, and heilig adapted to hold the two partsI of the chair arm securely together when positioned for use; and means to lock said screwsl from accidentally coming out of said plates.

2. An advertising device comprising a chair arm longitudinally 'and horizontally divided, the upper portion of said arm having an aperture ltherein and being removably secured to the other portion of the arm; a transparent panel secured in the outer portion of and closing said recess; means to means being adapted to permit the upperA portion of the arm to slide upon the lower portion to its position in use; and means secured to the lower portion to lock the parts together.
